ANCHOR ron PUMP TUBES.

Application led January 22, 1921. Serial No. 439,175.

To' all whom t may concern.'

Be it known that I, IVORTHY MARSH, a citizen of the United States, and a resident of Bristol, in the county of Harrison and State of Test Virginia, have invented certain new and useful Improvements in Anchors for Pump Tubes, of which the following is a specification.

My present invention relates generally to pump tubes and particularly to the pump tubes of deep wells in which pumping means are utilized above the perforate lower portions receiving the fiuid to be pumped.

In most wells at the present time the pump tubes are to some extent movable, the movement of the pumping means therein operating in practice to convey or to communicate more or less movement to the tube particularly in an up and down direction, which give rise to a decided disadvantage by stirring up sediment, sand and the like in the bottom of the well which finds its way into the tube and soon wears or cuts out the pump cups or leathers.

My invention has for its object the provision of an anchor which may rest upon the bottom of a well and is movably connected to the pump tube in such manner that the latter, spaced from the bottom of the well, may move without communicating such movement to the anchor and thus without stirring up sand and sediment with which the anchor is in contact.

With this general object my invention resides in a pump tubing anchor having the construction, operation and advantages of that shown in the 4accompanying drawing and outlined in the following specification.

In the drawing,

Figure 1 is a side elevation illustrating the practical application of my invention,

Figure 2 is a longitudinal section through the lower portion of a pump tube and through certain of the parts of my invention operatively connected thereto, and,

Figure 3 is a cross section taken on line 3-3 of Figure 2.

Referring now to these figures my invention proposes an attachment for the lower perforate portion 10 of a pump tube, the latter of which may be held or suspended in any suitable manner within a well, said attachment consisting of an axially bored supporting member 11, rigidly connected to the tube end, and movably supporting therein the upper head 12 of an anchor stem 13, the

lower end of which stem is attached to an anchor in sections 14 and 15, each preferably of solid cylindrical form, coupled by a connecting member 1G which will permit of the use of longer or shorter sections as required under particular circumstances as well as for adjustment of the length of the anchor.

As shown in Figure 2 I preferably provide the lower end of the tube 10 with external threads, receiving one internally threaded end of a tubular coupling 17 whose opposite internally threaded end receives the upper end of the tubular supporting member 11. The lower end of this supporting member 11 is contracted, having an aperture of less diameter than the head 12 and of greater diameter than the stem 13 depending through the aperture from the head, it being thus obvious that the head 12 can move up and down within the tubular supporting member' 11 whose bore is of a diameter greater than that of the head, without danger of displacement from the supporting member.

In the first instance the lower end of the stem is extended downwardly through the supporting member 11, its said lower end being threaded as at 18 for engagement in a threaded bore at the upper end of the inner section 14 of the anchor.

It thus becomes obvious that in operation the lower end of the lower section 15 of the anchor head may rest directly upon the bottom of a well as in Figure 1, the lower end of the apertured tube 10 being spaced above the well bottom and movable in the well upon the communication of movement thereto from the movement of the pumping elements usually employed therein, such movement being relative to the anchor, without moving the latter and thus without stirring up or otherwise disturbing the sediment and sand in the well bottom.

In this way I provide in a simple and effective manner for the continuous operation of wells, particularly deep wells, without the common disadvantages with respect to frequent replacement of the pump cups or leathers.

I claim:

1. An anchor for pump tubes including a tubular supporting member, a stem having an upper head of reduced diameter with respect to, and movable freely in, the supportingl member, and an anchor head at the lower end of the stem including a pair of length= wise solid sections and a coupling ring adjustably connecting said sections es described. v

2. The combination with e ypump lcube 5 having threads at its lower end, 0i a tubular supporting member depending from the lower end of the tube, a tubular coupling having threaded connection with the tube and Jche said supporting member, a stem 10 movably extending through the base of the WORTHY MARSH.
